The SeaWhat do you know about the sea?We know that it looks very pretty when the sun is shining on it.We also know that it can be very rough when there is a strong wind.What other things do we know about it?The first thing to remember is that the sea is very big.When you look at the map of the world you will find there is more water than land.The sea covers three quarters of the world.The sea is also very deep in some places.It is not deep everywhere.Some parts of the sea are very shal-low.But in some places the depth of the sea is very great.There is one spot,near Japan,where the sea is nearly 11 kilometers deep!The highest mountain in the world is about 9 kilometers high.If that mountainwere put into the sea at that place,there would be 2 kilometers of water above it！What a deep place!If you have swum in the sea,you know that it is salty.You can taste the salt,Rivers,which fi0w into the sea.carry salt from the land into the sea.Some parts of the sea are saltier than other parts,There i、one sea,called the Dead Sea,which is very salty.It is so salty that swimmers cannot sink!Fish cannot live in theDead Sea!In most parts of the sea,there are plenty of fishes and plants.Some live near the top of the sca.Othurslive deep down.There are millions of tiny living things that float in the sea.These floating things are so smallthat it is hard to see them.Many fish live by eating them.The sea can be very cold.Divers,who go deep down in the sea,know this.On the top the water may bewarm.When the diver goes downwards,the sea becomnes colder and colder. Another thing happens.When the diver goes deeper,the water above presses down on him.It squeezes him.Then the diver has to wear clothesmade of metal.But he cannot go very deep.Some people who wanted to go very deep used a very strong diving ship!They went down to the deepest part of the sea in it.They went down to a depth of eleven kilometers!Divers have to use a very strong diving ship when they want to go down to the deepest part of the seamainly because it is extremely cold there.A:RightB:WrongC:Not mentioned
